Avoid duplicating some of the escape-sequence processing here and use the
CLI function instead.

cli: Move readline character-processing to a state machine2023-01-16T19:14:11ZSimon Glasssjg@chromium.org2023-01-06T14:52:20Zurn:sha1:b08e9d4b6632a72b91306690d552c125b071441e
The current cread_line() function is very long. It handles the escape
processing inline. The menu command does similar processing but at the
character level, so there is some duplication.
Split the character processing into a new function cli_ch_process() which
processes individual characters and returns the resulting input character,
taking account of escape sequences. It requires the caller to set up and
maintain its state.
Update cread_line() to use this new function.
The only intended functional change is that an invalid escape sequence
does not add invalid/control characters into the input buffer, but instead
discards these.
